Not really. There's plenty of legitimate criticism for this game. Bed of Chaos is the worst boss in the series. Lost Izalith is poorly designed. They recycle a (lame) boss 3 times. The DLC recycles an entire level (Darkroot), and one of the more underwhelming ones from the base game at that. 20 Estus is too much and game-breaking, especially mixed with poise-tanking. The hitboxes for 4 Kings is ridiculous (both for giving or receiving hits), and it's a poorly designed boss overall, nothing more than a lame DPS race. The UI has a few issues, it's a bit clunky, especially the bottomless box. PvP has many issues, we could make a big list of that alone. I could go on.
The game having secret content, however, isn't among those.
May I suggest, don't be the 3125436th memelord making a Giantdad and be creative instead? Just a thought... ;)
